The SlingStudio Console offers a Wi-Fi health indicator of your SlingStudio setup, which provides a real-time indication of the Wi-Fi health of your system, taking into account the distance between the video sources and the SlingStudio unit, the distance between the Console and the SlingStudio unit, any interference with surrounding networks, bit rates selected, and physical barriers in between.
